Pennsylvania has reported its first case of the Zika virus through sexual transmission, according to the state’s health department

A Pennsylvania resident contracted Zika “from a mosquito while traveling outside of the state in an area where Zika transmission is occurring,” Secretary of Heath Dr.Karen Murphy said. That person then passed it via sexual transmission to their partner.

"In light of this, we remind residents to practice safe sex, especially if they have traveled to an area with Zika-infected mosquitoes," Murphy added. “Infections with the Zika virus may be present without symptoms. If you have traveled to an area where Zika virus is present, condoms or other barrier protection methods should be used during sex for 8 weeks upon return to prevent sexual transmission. Women who are pregnant or planning to become pregnant should discuss with their doctors any travel plans to Zika-affected locations.”

Zika can cause symptoms, such as fever, rash, joint pain and pinkeye. Though it’s rarely a serious threat, for pregnant women or women who plan to become pregnant, it is serious. Zika can cause birth defects including microcephaly, which causes newborns to be born with heads smaller than normal.


As of Aug, 29, there have been 95 confirmed cases of Zika in the state, according to the health department. There has been no transmission through local mosquitoes.
